QUIDEL SNFSOFIAQ Analyzer with Bluetooth Instructions

QUIDEL SNFSOFIAQ Analyzer with Bluetooth

OVERVIEW

A symbols glossary can be found at quidel.com/glossary.
Sofia Q is a small analyzer intended to be used with Sofia Cassette-based immunofluorescent in vitro diagnostic assays manufactured by Quidel Corporation and software (Quidel App) residing on an Apple iPhone manufactured by Apple. Procedural operation of the Sofia Q and test interpretation is performed by the App.
Sofia Q is intended for professional and laboratory use.
Connection of Sofia Q to a micro-USB compliant power source powers on the Sofia Q, rendering it both functional and discoverable via Bluetooth, the latter allowing pairing of the Sofia Q with the smartphone. The device pairs to the smartphone after the MAC address is retrieved from the label barcode at the bottom of the Sofia Q

Once the Sofia Q and the phone are paired via Bluetooth, the app can control the various functions necessary to perform a test as described below. The App provides instructions for the collection and manipulation of a biological sample with a swab, as well as the application to an immunofluorescent Assay (IFA) cassette. In addition, the temperature is read by an internal sensor to ensure that it is in the appropriate range (15 oC to 30 oC).

Upon proper insertion of a test cassette into the Sofia Q, a sensor triggers the assay countdown timer on the phone.
Once the countdown timer on the app reaches zero, images of the test strip are transferred to the iPhone where they are analyzed for QC metrics to determine whether the test is valid or invalid. If valid, the status of the test is determined, and a Positive or Negative test result is displayed on the screen of the phone. If invalid, an Invalid test result is displayed.
The image, the test raw data, and result can be uploaded in a dedicated server using the WIFI functionality of the phone, or maintained in the phone, within the App.
A multi-color indicator light is used to produce a visual cue that signifies the status of the Sofia Q.
The color and pattern combination and their meaning are as shown in Table 1 below:

Table 1. Sofia Q status light colors and meanings

INSTALLATION, SETUP AND OPERATION

Brief Warnings and Precautions

• Always operate Sofia Q on a surface that is level, dry, and not in direct sunlight.
•  Do not write on the barcode or surface of the Test Cassette.
•  Never move Sofia Q while there is a test in progress.
•  Use only the USB cable that was provided with Sofia Q.
•  Do not drop Sofia Q as it could damage the unit.
•  Contact Technical Support if the instrument is damaged.
•  Do not place Sofia Q instruments near a heat source.
•  Use of this equipment adjacent to or stacked with other equipment should be avoided because it could result in improper operation.

Setting Up the Sofia Q

•  Place Sofia Q on the counter or benchtop. Sofia Q is portable and can be moved to a suitable location for testing. Avoid direct sunlight
•  Connect the USB cable with an adapter (5 V AC/DC) that meets IEC 60601- 1- 2:2014 requirement.
•  To power down, unplug the Sofia Q.

Installing the Sofia Q App
In order to begin using the Sofia Q system, you will need to download the Sofia Q app. To download the app, search the name in the Apple App store, download and install. The application is currently compatible with iOS 13 and above for use on Apple iPhone 8 and later.

Alternatively, the QR code included here can be scanned using the camera on the iPhone for direct access to the App store.

Using the Sofia Q device
The Sofia Q can be set in two different modes (WALK AWAY Mode and READ NOW mode). The procedures for each mode are described below.

WALK AWAY Mode
In WALK AWAY Mode, the user immediately inserts the Test Cassette into the Sofia Q device. Positive and negative test results will be displayed at 15 minutes.

READ NOW Mode
Allow the test to develop for the full 15 minutes before placing in the Sofia Q device. The user first places the Test Cassette onto the counter or benchtop for 15 minutes (outside of Sofia Q). The user manually times this development step. The Test Cassette MUST remain on the bench for 15 minutes to get an accurate result. Then, the user inserts the Test Cassette into Sofia Q. In READ NOW Mode, Sofia Q will scan and display the test result within 1 minute.
Warning : Results must not be interpreted past 30 minutes after inoculation. Using Sofia Q past this time may result in false results.
